Silver Android Bullet Above Google's Android Building

Jeremy Joslin from Google posted a picture of what appears to be a new Android figure at Google. It is embedded above the Android building entrance. It kind of looks like a silver bullet but even cooler.

It seems to also be looking around, carefully watching over the Android building. Kind of like a robotic security guard.

It seems new because Jeremy said "Bugdroid appeared outside my lobby today" and I've never seen this before (maybe I didn't notice).
